You and your best friend and in the same math class finally it’s your junior year and you have seats next to each other. The class is kinda hard but the teacher has office hours from 3-5 on some days so you and her stay after to work. But she gets strangely close with him and starts to act different.
This spefic day you and her are in there and to be fair doing more talking then work but at some point you step out to go to a different teachers class to grab something.
by the time you return he is standing over the desk you and her share talking with her in a hush dark almost rough tone. You noticed he is touching her arm Something isn’t right. He noticed you and stepped back letting go of her arm, but the look he gives you is almost chilling. It’s a smirk somewhere between a look pushing your silence and something you can’t quite place.
You say nothing and find your seat to just finish your work and get going.
